With sentences, and a foreign language, I found it easy to teach my kids to start with a verb. If the word is already a verb, that's the easiest thing. If it's not, you have to find a verb that works well with that. I will give you one so you can see the process.

"Enthusiastic" is the word I'll choose, since PsyDAG already told you what that means.

Enthusiastic is an adjective. Almost any adjective, you can use the verb "to be."

First, ask the question, "Who?" In this case, "Who is enthusiastic?"

Answer: Matt
Matt is enthusiastic.

That's a very simple sentence. To make it more complex, keep asking questions. "When?" "Why?" etc.

Can I also add a word of advice. I used to work in a school where a teacher did not have a great grasp of english yet used to set questions like this. In his classes there were several very bright pupils who used to give answers to this type of problem using less familiar meanings of the words. The pupils used to complain to me as their Tutor when the teacher marked the answer wrong.

For example

The church of St Michaels is in a different peculiar to that of St James.
